How do I contact unity3D forum support?

I cant find a way to contact unity 3D forum support in any way.
And I cant post in the forum either.
It’s frustrating…

And not even a sub forum for support questions…

Sure there is.

That still doesnt fix the whole problem.

What is the whole problem? Replies are (intentionally) disabled for Collaboration. So things are working and you don’t have any problems posting that I can see.
